Adriana named after Adrien-Henri de Jussieu (1797-1853), a French botanist . Quadripartita from the Latin 'quadri' meaning four and 'partita' meaning parts, referring to the calyx with 4 sepals.

Distribution:

Found in coastal regions of South Australia in sandy soil often associated with calcrete, in open or disturbed coastal areas. Uncommon on the West Coast of South Australia. Also found in Western Australia and Victoria.

Collect ripe fruits when they become dull in colour and seeds are mature, hard. Keep a close eye on maturing fruit as it will open and release the seeds quickly.

Seed cleaning:

Place the fruits in a paper bag and leave to dry for 1 to 2 weeks, until they split. Then rub the capsules gently by hand to dislodge the seeds. Use a sieve to separate the unwanted material. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place.

Seed viability:

Seed viability can be variable and seeds are prone to predation. From two collections, the seed viability was average, ranging from 65% to 72%.

Seed germination:

This species has physiological dormancy that needs to be overcome for the seed to germinate.
